# Olypsys Measure vs AMT

The clearest difference is rating: AMT at 5.0 against Olypsys Measure's 3.2. AMT also leads on in-app purchases (none vs 3) and update cadence (every 6 days vs every 4 weeks). Olypsys Measure's advantage is ratings volume (6 vs 1). On price, ads and iOS requirement there is nothing between them.

Both are free to download. Olypsys Measure sells 3 in-app purchases, starting at $10.00 per month. AMT asks for nothing beyond the download.

AMT holds the better App Store score, 5.0 against 3.2. That said, the two scores are not equally well evidenced: Olypsys Measure has 6 ratings behind it against 1, so its average is the more settled of the two.

Olypsys Measure ships an update every 4 weeks, AMT every 6 days. The most recent releases landed on October 21, 2026 and October 27, 2026 respectively.
